The folks at Biolite sent me a PowerLight Mini. It's a rechargeable LED lantern with a 1350 mAh battery. It has a burn time of over 50 hours in low light mode, and 5 hours in high mode. It can also be used to charge your phone.
My favorite thing about it is the design. It's very cute – it has a retro feel that reminds me of a Japanese transistor radio and a Star Trek communicator. The body is stainless steel and it feels solid. I've been using it to read books at night. In the video above, the Biolite team shows how they designed the PowerLight Mini.
